IMPROVEMENT IN' WATER-ELVTORS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, ZEPHANIAH Lookwoon, ofSaratoga Springs, in the county of Saratoga, and State of .New York,have invented a new and improved `Serpentine-Chain Elevator, Lever,Fulcrum, and Spring; and I do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, and the letters of reference marked thereon. l

The nature of my invention consists in a chain elevator, which, whenused, rathers from the bottom of the chain upwards, by folding of thelinks.

The bars which make up the links ofgsaid chain are not straight, butslightly crooked, or turned crossing each other, and fastened togetherfmthe centre. The lower end of each ,bar in a link is fastened to theupper end of the opposite bar in the next link below.

The chain can be used for drawing water from the bottom of wells, or anyother use for which elevators are commonly used.

Said chain, in folding, when used, has a serpentine movement, inconsequence of the curve in fnlcrum and bars composing the links alwayscommencing to fold or gather at4 the bottom, and continuing to fold'-upwards to the top of the chain, taking up and leaving noslack whenfully folded.-

The chain is folded or gathered'by a lever and, fuls.

crum, fastened to the second link of chain.

A', in the plan or draught, is the lever, which, when pressed down, setsthe whole machineryin motion.

A A is a crooked -or serpentine fulcrinn, on which the lever is attachedin working.

B is a dat bar, crooked or curved, and connecting fulcrum A with D, or apartofiirst link in chain.

E is the top link, attached to the cross-bars at the y 'top of chain, atD-being attached to D, fastening at the bottom to the end ofthe fulcrum.

O is the spring, fastened under the rivet at I), each lend beingattached tol G.

4 G is a rivet, or fastening of the end of links in chain together. l

F is the bail, attached to the bucket, or\other tub or dish containingthe load to be attached.

.I The reason why my improved chain gathers faster from the bottom thanat the top, is the change of pivot of each pair of links, by means ofwhich the lower ones are closed before the upper ones, as is clearlyshown in the drawings. The links having the curved shape shown, fold npwithin each other, and thus gather the entire chain up close.

I do not claim, broadly, a lazy-tongs, or compound lever, for thepurpose of depressing or elevating a. Ybucket, as I am well aware thatthis has been patented byJ. C. Barrett, July 3, 1866. invention ismerely an improvement on the same; and

What I claim as new, and desire to secure by Let` ters Patent, is-

1. The lazy-tongs, or compound lever, for elevating Watergwhen the linksand the lever are made in the shape shown, and pivoted in such a mannerthat-the chain shall gather faster from the bottom than from lthe top. i

2. Incombination with the above, the spring C, when arranged to operateas shown and described.
